Problems solved by technology

However, unlike other freshwater perch (such as gemstone perch) and sea bass (barramundi), the application of nutritional feed to raise California perch is prone to the following problems: (1) California perch is not as fond of nutrient feed as chilled bait; (2) California perch is not as good as chilled bait; The utilization rate of carbohydrates is not high, but due to the limitation of current domestic production equipment and technology, the level of feed carbohydrates is difficult to reduce
At present, the penetration rate of special feed for California perch in the market is not high, and it is often replaced by ordinary carnivorous fish feed, which does not meet the nutritional needs of California perch, seriously affecting the use of nutritional feed

Abstract

The invention provides a formula of a nutrient feed for micropterus salmoides. The nutrient feed consists of the following components in parts by weight of air-dried substances: 8-12 parts of flour, 30-50 parts of fish meal, 4-6 parts of whole shrimp powder, 3-8 parts of chicken meat powder, 2-4 parts of corn protein powder, 2-5 parts of vital wheat gluten, 2-4 parts of blood powder, 9-12 parts ofdehulled soybean meal, 4-7 parts of soy protein concentrate, 7-10 parts of soybean oil, 0.5-1.5 parts of phosphatide oil, 1-2.5 parts of calcium dihydrogen phosphate, 0.1-0.5 part of L-lysine, 0.1-0.2 part of DL-methionine, 0.01-0.05 part of vitamin C and 0.5-1 part of choline chloride. Compared with an ordinary feed, the nutrient feed for adult micropterus salmoides disclosed by the invention has the advantages that the dosage of fish meal is reduced to 50% or below, and protein raw materials high in food calling properties for the micropterus salmoides are preferably selected, so that the food calling properties of the feed are good, the adult micropterus salmoides likes to eat the feed, and bred adult micropterus salmoides is high in growth speed, good in somatotype and low in cost.

Description

technical field [0001] The invention belongs to the field of fish feed, and in particular relates to a feed formula for California perch. technical background [0002] California perch, also known as largemouth bass, belongs to the family Centrarchidae of the order Perciformes. It originated in California, USA, and was introduced to China in the early 1980s. California perch has the advantages of fast growth, less disease, low temperature resistance, less thorns, delicious taste and rich nutrition, and is very popular in the market. In recent years, California perch has become one of the important freshwater aquaculture species in my country. However, in recent years, problems such as environmental pollution and frequent occurrence of diseases caused by the farming mode of California perch mainly fed with chilled fish in my country have affected the sustainable development of the California perch aquaculture industry. Gradually popularize and apply in production, there will...
